Hi cyclists. Got a wheel with Nexus 7 hub. Problem is that the cassette joint jams. It shifst up just fine but jams when shifting back. Cleaning the cassette joint does not solve the problem. The hub itself has no play or is not tightened to heavily. The wheel spins just fine. Got any idea what the problem might be? Is it fixable or do I need a new internal hub?

I’ve had two Nexus 7’s with the exact same issue. Unfortunately, I did not find any other solution than a full replacement. I decided to open one, and I saw a metal piece sticking out causing friction on the lever. As if that metal piece was supposed to be deeper in the system and it moved out after two years of use.
Never made sense of it.
I’m following this thread closely to hopefully learn more too.
It sounds like something internal to me if the cassette joint itself doesnt have the binding when cleaned etc.. I don’t really know about the internals tbh sounds like whatever return mechanism is bad. Cyclemonkey is a great resource for igh stuff (im not plugging them just used them for rohloff stuff). Believe they do service of all kinds and prob would have an idea if you emailed them w the question.
also curious to learn whats up I have yet to tackle this problem myself
